Abstract Objective To investigate the diagnostic value of ultrasonography, CT features and combined application of cervical lymph node metastasis in papillary thyroid carcinoma (PTC). Methods A total of 139 PTC patients diagnosed in the Affiliated Hospital of Guizhou Medical University from January 2019 to December 2021 were selected and divided into 66 patients with cervical lymph node metastasis (metastatic group) and 73 patients with no cervical lymph node metastasis (non-metastatic group) according to the results of cervical lymph node puncture. Preoperative ultrasound and CT imaging data of the two groups were retrospectively analyzed, the imaging features of PTC lesions and metastatic lymph nodes were compared between the two groups, and the value of the two methods in the diagnosis of cervical lymph node metastasis of PTC was calculated. Results The difference between the two groups was statistically significant (P<0.05) in the ratio of lymph node margin defect, vertical and horizontal diameter, portal echo, lymph node shape, and echo feature ratio. There were significant differences between the two groups in lymph node internal capsular necrosis, granular calcification, lymph node margin enhancement, lymph node morphology, lymph node and surrounding tissue, and lymph node elongated diameter line ratio(P<0.05). Conclusion After cervical lymph node metastasis of PTC, ultrasound, and CT have obvious characteristics, and the combined application of the two can improve the diagnostic efficiency.
